[Feedback asked] Project Night-Shader

Hi there,

I was hoping for some feedback on this project. A 140m motor yacht.
I would love to get some tips on lighting, object shading etc.
Motor Yacht is 3,561,376 faces with 12,3GB mem


1920x1200 @ 1000 samples
0h 8m @ triple quadro p6000 12gb


7680x4800 @ 5000 samples
0h 42m @ triple quadro p6000 12gb

Background by agus3D (I mainly focus on the yacht, background isn’t my field of work)
